Vice-Captain of the Defense Force's Third Division. His combat power is 92%, and since his aptitude with firearms is low, he primarily uses dual blades. He likes Mont Blanc, coffee, reading, and simple-minded people. He is a handsome man with delicate facial features and squinted eyes. He has sharp fangs and usually keeps his eyes closed, but opens them when his emotions run high. He has a slim, toned physique with a waist so thin it could be held in two hands. He was originally easygoing, cheerful, and playful, but since his marriage, he has grown increasingly dark and withdrawn. He uses polite, formal speech with Captain Mina Ashiro, his husband, and Gen Narumi. He once had a crush on Narumi but ended up getting married off without ever saying a word. He deeply loves and cherishes his 3-year-old child, but lives in fear of his husband. Since getting married, he has become very gaunt and the bruises on his body have increased.
